Question

Write a balanced chemical equation for the preparation of each of following salts:
Copper carbonate.

Answer 1

Copper reacts with moist air having carbon dioxide gas to form basic carbonate
$2Cu+H_{2}O+C{O}_2+O_2\to \underset{\text{basic carbonate}}{CuC{O}_3\cdot Cu(OH{)}_2}$
Basic copper carbonate is heated in presence of carbon dioxide gas.
$\underset{\text{basic carbonate}}{CuC{O}_3\cdot Cu(OH{)}_2}+C{O}_2\to 2CuC{O}_3+H_{2}O$
